APPLICATIONS · BUS
One bus, one network,
one control room.
Everything NSS puts on board a bus, and how that onboard network reaches the PCC.
The matrix by vehicle type
What goes into an NSS bus
Destination Indicators
SC762 and LC ranges — homologated for road use.
TCU Consoles
Driving position — Ethernet–RS485 bridge, bus range.
SENTINEL
Onboard CCTV, continuous recording per compartment.
Passenger Counter
Count per door, ETH or RS-485 variant.
Ethernet Switches
Onboard network, managed or unmanaged, with or without PoE.
NCG · CAN Gateway
CAN/J1939 acquisition, ITxPT services — buses, electric buses and BRT.
Vehicle 5G Gateway
Cellular connectivity and onboard Ethernet/Wi-Fi backbone.
Lighting
LCU + LED Driver, DALI-2 — bars, strips and tubular fixtures.
Onboard network → PCC
From the CAN bus to the control room
The NCG reads the vehicle's CAN/J1939 bus and distributes the data over the onboard Ethernet network, in the format of the ITxPT standards; the 5G Gateway carries that network to the cellular network. On the other side is the SAE — the onboard system that runs the operation inside the bus — and it's the SAE that talks to the PCC: it reports position, trip, status and events, and gets back duty assignments, notices and timetable changes.
